Application December 15, 1948, Serial No. 65,409

7 Claims.

This invention relates to windows and more particularly to those of the awning type.

Such awning type windows have heretofore been constructed to include a frame having a plurality of sashes, each sash being pivotally hung on a pair of supporting levers which are pivotally mounted to the frame and provide fulcrum means for the sashes. An operating bar is also provided at each side of the frame and pivotally secured to each sash. This operating bar is actuated to open or close the window by raising or lowering the sashes and thereby swinging them in unison on the fulcrum means.

In order to assure uniform operation and proper closing action of the said sashes, it is important that the said fulcruming levers be accurately mounted so that, when the sashes are closed, they will bear uniformly and evenly against the window frame on all sides. This has been found difiicult to accomplish for the reason that any twisting or distorting of the frame in handling and in the installation thereof may cause an improper fit between the sashes and the frame.

In order to overcome this difficulty and assure a proper fit for the sashes after the window has been installed, it is desirable to provide suitable means whereby the sashes may be adjusted for proper fit after the frame has been installed.

An object of this invention therefore is to provide an awning type window having fulcruming bars for the sashes which are adapted to be adjusted as to their effective length so as to provide for uniform and full closing of said sashes against the window frame.

A further object of the invention is to provide such adjusting means which may be operated while the window is closed, so that the sashes can be adjusted to properly fit against the frame.

A further object of the invention is to provide such adjusting means which are easy to use, economical in their manufacture and highly efficient in their operation.

Further objects and advantages of this invention will be more clearly understood from the following description and from the accompanying illustrations in which:

Fig. l is a sectional side view, on line l-l of Fig. 3, showing a window embodying my invention in closed position.

Fig. 2 is a similar view showing the said window in open position.

Fig. 3 is a rear view of the window, partly in section on line 33 of Fig. 1, and with some of the parts omitted.

Fig. 4 is an enlarged fragmentary view of the adjusting means comprising my invention.

Fig. 5 is a further enlarged plan view thereof on line 5-5 of Fig. 4.

Fig. 6 is an elevational side view of a fulcruming plate used in my invention.

In the embodiment illustrated in the drawings, the numeral 5 denotes a window frame having a pair of sashes 6-6 pivotally mounted therein. The said sashes each have a supporting plate 1 secured to the upper ends of the opposite sides thereof, by means of screws 8. These plates are each pivotally connected at In to a supporting and operating bar 9 that is vertic ally slidable in grooves along the sides of the frame 5.

To each of the said plates I there is pivotally secured, at I I, a supporting fulcrum bar 12 which is pivotally mounted at l3 in a supporting plate l4 that is secured to the side of the frame.

The operating and supporting bar 9 has a series of teeth l5, in the lower portion thereof, which mesh with a gear l6 that is mounted on a connecting shaft I! and rotated by means of a worm I8 which is rotatable by a crank lever I9.

The shaft I! is rotatably mounted at its opposite ends in lower supporting plates 20 to which the bars I2 of the lower sash are also pivotally mounted. The said shaft extends across the window frame and has one of the gears H5 at each of its opposite ends.

In the operation of the above described awning type window; assuming that the window is in closed position as illustrated in Fig.1, rotation of the crank lever IS in a conterclockwise direction will rotate the gears I6 and Iii-a and cause the operating bars 9-9 to move downwardly in the window frame. This will cause the window sashes to be lowered in the frame and to swing outwardly in unison upon the ends of the bars I2l2 to open position as illustrated in Fig. 2.

Inorder to assure proper fit between the opposite sides of the sashes and the window frame, so that the sashes will be evenly and uniformly v closed, I provide novel means for adjusting the fulcrum bars l2-l 2 so as to, in effect, change their lengths to vary the distance between their 3 threaded to the bar l2. The pivot l3-a also extends through a slot 24 in the said bar 12.

The plate 14 is provided with an opening 25 to render the head of the adjusting screw 22 accessible for the adjustment of the bar I2.

When it is desired to adjust the sashes so that they will properly fit against the frame, the said sashes are first brought to closed position so that they will engage the window frame. Those sashes, or the sides of any sash, which do not properly engage the window frame in fully closed position can then be adjusted by loosening the screw 22, pulling the said side of the sash against the frame, and then retightening the said-screw 22. This will in effect change'the length of the bar 12 to retain the sash squarely against the frame.

It will be understood from the above description that the distance between the pivotal'points I I and 13 remains constant at all times and that, in making an adjustment, only the length of a bar l2 is'altered. v

In the operation ofthe window, the said bars (2 will be carried on the bearing plates M and prevented from turning on the screw'22'bymeans of the connection between the'sides'of theslot 24 and the pivot member 13 0,. 7

From the above description, it will be readily understood that my invention provides an awning type window in which one or more sashes are swung inunison and may be readily adjusted toenable full and uniform closing of all of'said sashes. 4 i

It will also be understoodthateach of the adjusting means is readily accessible since the head of the adjustment s :rew"22 is alv'vays exposed through the opening- 25. "This permits'the adjustment of the'sas'hes when they are in closed position so that a considerable amount" of labor and expense will be saved by reason of thejfact that any necessary'adjustment of thesaid sashes may be made after the window is installed.

l. A window comprising a frame, a pl'uralityof sashes pivotally mounted in said frame, means connecting said sashes for swinging them in unison in said frame, and fulcrum members for said sashes pivotally connected to-salidsishes and frame; at least one of thesaid fulcrum members being adjustable between the pivotal points thereof to provide for fully closing its respective sash upon full closing of another sash in said frame.

2. A window of the'-'character described cornprising a frame, a plurality of swinging sashes pivotally mounted in said'frame,means connecting said sashes for causing'them to swing in unison in said frame and 's'idearms pivotally'connected to said frame and to said sashes; at least one of said side arms being adjustable for-varying its length between said pivotal connections to thereby cause said sashes to ocoupy'fully closed positions.

3. A window of the character described comprising a frame, a plurality'of sashes mounted for swinging movement in said frame; means connecting said sashes whereby the same willswing in unison, each of said sashesbeing pivotally mounted to a supporting and operating bar,- a pair of supporting side 'arms pivotally' secured to said sash, a pair of bearing'plats pivotally mounted on the frame, and adjustable means connecting each of said arms to its respective bearing plate to permit adjustment thereof to vary its effective length between the pivotal point of said bearing plate and the pivotal connection between said arm and the sash to provide for full closing of each of said sashes upon the closing of the other sash.

4. A window of the character described comprising a frame, a pair of sashes mounted on said frame, a pair of operating bars pivotally supporting said sashes, and a pair of supporting arms pivotally connected to said frame and to said sashes; the pivotal connection between each of said supporting arms and frame being provided "by means of a separate bearing member pivotally sash, each of said arms being pivotally connected to the sash and to the window frame, the connection between said arm and the window frame includinga bearing plate pivotally secured to the ra'me and an adjustable connection between said plate and the arm for varying the length of the arm to permit adjustment of said sash when I in closed position to provide for uniform fit between the opposite sides of the sash and the frame,

6. A window as set forth in claim 3 wherein the adjustable connection includes a portion on said 'arm having a slot for slidably receiving a pivot member forming the pivotal connection of tho-hearing plate, the said bearing plate having a slot extending therethrough, and a screw member extending through the said slot in the bearing plate and threaded to the said arm.

'7. A window as set forth'in claim 3 wherein the said adjustable connection includes a supporting'plate secured to the window frame, a pivot member secured to said supporting plate, a bearing plate pivotally supportedby said pivot member, and an end portion on side arm having a slot therein'receivingsaid'pivot member, the

said bearing plate also having a slot therethrough, a screw member extending through said slot in the bearing plate and threaded tothe-end-portion of the arm' and the-said supporting plate having an opening rendering 1 the end of said i screw member accessible when the window'is in closedposition.
